Haven't had the opportunity to look through a LRHS or ERS. Have never had any success with and SWFA scopes, and they are right down the road form me. Glass is very subjective. There are objective ways to measure glass quality, but they leave a lot to be desired. So here is my take. I have 2 NF Atacr scopes. Per my application of local matches, training, and hunting in Texas, I see no benefit in the Atacr over the HDMR2. There is a $1,000 price difference between them and I can't figure out why. Trust me when I say this surprises no one more than me. Who would have though Bushnell would be able to make a quality scope. Not me. I still like my NF scopes, no plans on getting rid of them. But I defiantly won't be buying anymore. No, I'm not a brand snob either. I have Leupold, NF, Vortex, and Bushnell. Matter of fact I just bought a NF SHV F1 last week. I have a Vortex PST Gen 2 on my 22lr, good glass, just doesn't feel as refined as the HDMR2. But I would caution you agains the first generation HDMR or DMR. The 2nd generation are miles ahead in function over the gen 1. Hope this helps.
